TO ALL WHOM `I'I MAY CONCERN: v i ,u

Be it known that I, WILLIAM Werven, of Phoenixville, in the county of Chester, and State of Bonnsylyniiie, have invented new and luseful Improvements in `Spring :Bed- Bottoms; and I do hereby declare 9n- `to be a full `and exact description of the saine, reference being had to the accompanying drawing, `nialiipg pdrt this speciication, and in Whichi i Figure 1 is a perspective view oi' a bedstead with my improved bed bottom attached.'

Figures 2 and 3 are detachedA views of parts hereinafter described.v

Similar letters of reference indicate corresponding parts in the several figures.

My invention consists in a novel mannerofplacng. the spiral springs in lateral holesin the bed-fratr1eg` connecting the wires to the springs by means of links, and in keepi'g the Wires apart laterally andat equal t tanoesfrom each other,lby means of loops formed 'on onetor more of the wires which run from the head to` the p,

foot end of the bed.

In thc accompanying drawings, A may represent the head-beard, and ,B the `foot-ligoard of a bedstead.`

C C C C are the bed-posts, which are `hinged at c to the frame D Dl D, so that the bedstead can `beeasily folded, moved, or stored away, `whenever desired. t `Into the sides D D," I),2 D, of the frame, bore hqles `pf just suiiicicnt size to admit the spiral springs E, (see iig. 2.) These holes do not go entirely through `the framesgbxit leave suiicient wood between the base of the hole and the inner side of lthe frame to form a strong bearing for; i

the inner endof the spiral spring.l Through this bearing, at its centre, I boreasinall hole, a, toallqvvtlie` curved piece F to easily slide in and out.` At the outer end of this piece of wire, F, is a button, f, vvhich holds e. washer,

t z', the washer forming a bearing for the `oiter end of the spring E.` [,lfhe holes'arecovered on the outside of frame by a thin strip of ywood, G, which is nailed, screwed, or otherwise fastened to the frame.` inner end of the curved wire F is bent under, so as to form a loop, g, and is connected to the bottom Wires H, I, and l i i means of the links L, as shown in figs. 1, 2, and 3. v'Ihese links consist of short pieces wirebent into shape, one end hooking into the loop g, of the wire F, and the other into the loops It, at the ends of the bottoni wires 11,1, and K, the last-mentioned loops 7L being bent under in the same manner asthe loop g. The bottoni p wires I arcfproperly the supporting wires, whilst the wires H act asV braces for them, and the wires K serveto hold then laterally in their positions, and at a certain distance from each other. I do not limit myself to any i number of either of these wires, for I propose to use more or less of cach as circumstances may require.` f i nire K, passed from the head to the foot. end of the bed-frame, is bent over and ,around each supporting wire I, forming a loop, 7c, in which the wire I is not only supported or braced, but held in a laterally steady position. It will be readily understood that thc-curving of the wire F serves a double purpose. Firstlyit naturally follows the line of motion of the bed bottomwhen any weight is placed on the same, and when the spring is` C compressed by it, as'secn in red lines in fig. 2, thus dividing the strain on the Wirel equally over its Whole p length, While,` if the same were straight, most of the strain would be on 'that point` on the wire F just outside of il the orifice a, having a tendency to bend and break it.l I am also enabled, by thus dividing the` strain, tense a` much smaller wire than I could do otherwise.- Secondly, it keeps the loops y constantly under its curvedpart,

and consequently the link- L in a iiat position, and the loops h placed similar tothe loopsg, so that thehook ends of these loops and. links can'nin no cas, and by no violent pressing dovvn of the spring bed bottom, catch into` i and tear the ticking of the mattress, Whichis frequently the casein wire bottom beds, where no provision is made i Y to prevent it. The links L perform an important service in my bed bottom, as they give elasticity to and pref,

vent the breaking of the wires II, I, and K, on the ends of which, were they directly attached; to the loops g;`

4'there would be an additional strain when depressed near the loops 71., as will be easily understood. By enclosing the springs E in the lateral holes in the' bed-frame I am enabled to preserve them much longer. than `when they f nre attached-on the outside ofV the frame, as no dust or dirt can settle in their folds, and: they are in great measure protected from the moisture of the atmosphere7 which is very apt to corrode andmake them brittle Furthermore, as the springs lie in holes of just sufhcient size to hold them, they cannot get out of order or. bren-h, having but just lroom enough to expand fully. The advantages of constructing my bed on the plan proposed, are many. It is easily made and very durable. Shouldanything give way the repairs can be made in a fev(` moments. If it is necessary to replacea spring the hatten or piece G is removed, whenthe springs are all exposed to view and easily taken out and replaced. The movement of the bed is perfectly uniform, as by means of the curved wire F and link L, the cross-wires H, I, and K, nre kept constantly in n horizontal position, without bending nt their ends when pressed down. l

Hit-ving thus described my invention, what I claim as new, and desire to secure by Letters Patent, is- The combination of the spiral springs E, curved wires F, yprovided with buttonsj', sind loops g, washers z', links L, supporting wires H I, and looped wires K, substantially :Ls and for the purposes described.
